I do a lot of Exercism.io exercises, I always initiate a Git repo, so I can experiment when my proposed solution gets stuck or I want to try another path. I do not branch a lot, but I have the option and I do it once in a while.
For my GitHub projects I try to keep everything in branches and even send PRs to myself, I got that as a recommendation once from somewhere and it works great.
